This isn’t a case of odd duergar who decides to become a ranger. This is a case of diametric opposition more akin to AP wants to be a rager but keep all his spells.

Humans are, above all, adaptable. They rise to the occasion exceeding the rest of the race in areas critical to the success of their craft. A half-elf uses human adaptability and elven quickness to rival all but the birds themselves.

For genuine exploring you need cure disease or a poultice. You also need significant damage reduction. These things are hard to get without empowerment or battle cabal.
Anyone, what you're looking for is probably N/N bard with periapts, talismans and scrolls.
If you want something even more casual, I guess give something like arial hunter explorer a shot.
